404 REPORT OF THE COMMISSIONER OF AGRICULTURE. 



tized portions of tlie pulmonal tissue, which caused the lungs to fill the 

 whole thoracic cavity. The substance of the heart appeared to be in a 

 state of congestion, and not only the auricles, but also the ventricles of 

 that organ presented their capillaries turgid with blood. In the abdom- 

 inal cavity the only morbid changes that could be found consisted in 

 incipient ulceration in the mucous membrane of the stomach. No en- 

 tozoa or worms, neither in the bronchiiie nor in the intestines. 



Mr. Morris promisetl, at my request, to divide his herd into several 

 lots, and to separate the healthy animals from the diseased ones. I left 

 two pounds of carbolic acid to be given, to the healthy animals in the 

 water for drinking, and a quantity of hyposulphite of soda for the 

 diseased ones. 



Went again to Mr. Morris's place on November 3. My directions had 

 been complied with. The whole herd had, been divided into six differ- 

 ent lots, the diseased animals by themselves and the healthy animals by 

 themselves, in different yards or inclosures. The medicines, the car- 

 bolic acid and the hyposulphite of soda, had been used and no deaths 

 had occurred. It even seemed as if the appetites of the diseased ani- 

 mals had somewhat improved, and as if the coughing had become a lit- 

 tle less. Still how much of the apparent improvement should be accred- 

 ited to the medicines, how much to the clear and cold atmosphere — the 

 thermometer indicated several degrees below the freezing point ; how 

 much to the continued diy weather — it had not rained for several 

 weeks ; and how much to the strict separation and the division of the 

 large herd into smaller lots, is very difficult to determine. At any rate 

 the disease prevailed in a very mild form in Mr. Morris's herd. 



My next visit was on November 7, when I found the strict separation 

 broken up on account of the scarcity of water — it had not rained for 

 nearly a month. During the night the pigs were still kept in their 

 respective pens and yards, but during the day four of the diflterent lota 

 had access to a common trough to get water. The arrangement was as 

 follows: One well, separated by a fence, supplied two troughs with 

 water. One of the troughs was placed in a swine-yard, occupied by 

 about one hundred healthy hogs and pigs, and the other one was out- 

 side and furnished water for the four lots mentioned. The hogs and 

 shoats recently bought by Mr. Morris, as before mentioned, composed 

 the sixth lot, and were kept by themselves in the barn-yard, more than 

 forty rods distant from the other swine-yards, and received their water 

 for drinking fiom a well near the barn. I found nearly one hundred 

 hogs and pigs, or about 25 per cent, of the whole herd, more or less 

 coughing, a few thumping, a few limping, and some very much ema- 

 ciated, but only one animal dead. The carbolic acid had been used 

 freely in the water ibr drinking, and Mr. Morris is inclined to ascribe 

 the unusual mildness of the disease (caused undoubtedly by a combina- 

 tion of circumstances) to its effect. Left more carbolic acid and some 

 hyposulphite of soda. 



On November 8 it commenced to rain, and continued for a week. 



Went again to Mr. Morris' place on November 18. Found about 50 

 per cent, of the whole herd affected and coughing, but the disease was 

 of such a mild type that only three animals, which had been castrated, 

 had died, as has been mentioned before, or rather had been killed by 

 Mr. Morris when he found them past recovery. One of these tliree had 

 been dead only a day and had not yet been buried. It was in a first- 

 rate state of preservation, and therefore a good subject for post-nio7'tem 

 examination. Morbid changes: Externally, a little redness of the skin 

 on the lower surface of the body and between the fore-legs. Internally,
